[0002] The black-spotted catfish (Pseudosphagidae) is a fish that lives in the middle and upper reaches of the Yarlung Zangbo River. It belongs to the genus Pseudosphagidae, family Siluriformes. This fish is a Class II nationally protected wild animal. It is primarily found in the Yarlung Zangbo River basin at altitudes between 2,800 and 4,200 meters and is endemic to the region. The black-spotted catfish is most unique in its dual livers. In addition to a normal liver within the abdominal cavity, it also has a special organ, the extra-abdominal liver, located between the skin and the body wall muscles. This extra-abdominal liver is connected to the abdominal liver and performs the same function. The biological characteristics and ecological habits of the black-spotted catfish are also unique. Its species divergence is directly related to the uplift of the Qinghai-Tibet Plateau, allowing it to adapt to the unique environment of the plateau. The black-spotted catfish grows slowly, matures late, and has low individual reproductive capacity. Therefore, research on artificial breeding technology and the conservation of germplasm resources are of positive significance for protecting biodiversity in the Yarlung Zangbo River basin.
